I am running a custom compiled 2.6.24 kernel on a 64-bit Intel system and had no issues compling and running kvm-75.

I downloaded kvm-76 and compiled and installed it, but I cannot get the modules to load properly.

I have temporarily gone back to kvm-75.

I am seeing this output in dmesg:

Seems you enabled CONFIG_DMAR in host kernel side? In theory, we should use CONFIG_DMAR with newly VT-d support in KVM, but the problem now is that userspace including compile option is not ready, so here comes compile problem.

If you want to try kvm-76, you may try to disable CONFIG_DMAR in host kernel. Or just wait to userspace VT-d support merge (of course you can add vtd.c manually in Kbuild to overcome this compile issue). :)

Thank you for the information. I apologize for posting twice to the mailing list on the same issue. I was just trying to add some additional information.

Could you tell me how to edit the Kbuild file for this purpose? I can also recompile my kernel, but that's a bit more difficult.

Thanks in advance,
Sterling Windmill

Add vtd.c to kvm-userspace/kernel/x86/Kbuild kvm-objs item should get it done.

#4 lore raw

It seems as though I need to insert vtd.o instead of vtd.c

My Kbuild file now looks like this:

# trick to get the kvm-specific CONFIG_KVM_* definitions,
# because the kernel source tree won't have them
include $(obj)/../config.kbuild

obj-m := kvm.o kvm-intel.o kvm-amd.o

kvm-objs := vtd.o kvm_main.o x86.o mmu.o x86_emulate.o ../anon_inodes.o irq.o i8    259.o \
         lapic.o ioapic.o preempt.o i8254.o coalesced_mmio.o \
         ../external-module-compat.o

ifeq ($(EXT_CONFIG_KVM_TRACE),y)
kvm-objs += kvm_trace.o
endif
kvm-intel-objs := vmx.o vmx-debug.o ../external-module-compat.o kvm-amd-objs := svm.o ../external-module-compat.o

CFLAGS_kvm_main.o = -DKVM_MAIN

The modules do compile with this option specified.

Unfortunately, the error inserting the modules still persists.

Any other ideas?

Yeah... That's vtd.o :)

And I forgot, if you want to compile vtd.c, you need compile kvm kernel space rather than other kernel version for we modified host kernel side.

Sorry for I don't have a box by hand so that I can't check every detail...

I suppose you want to keep your kernel? Maybe disable CONFIG_DMAR is more easy...

I believe the following ones just because kvm.ko modules can't be insert in...

In reply to Sheng Yang

I am able to run kvm-76 after recompiling my kernel with DMAR unset.

Thanks for the help!
